Operating Systems OS X (Apple) Help in explaining this echo conundrum. Post 302993799 by Corona688 on Tuesday 14th of March 2017 01:46:56 PM

'echo' is not consistent or portable between different shells. Sometimes you get newlines, sometimes you get \n, sometimes you only get newlines when you ask for them with echo -e, and sometimes you can't get newlines out no matter what you do (i.e. /bin/sh on solaris). Given OSX's nextstep/mach lineage, I'll wild-guess that their /bin/sh is meant to resemble an old Bourne from BSD.

printf is a lot more consistent.
